Product Description

Pressure Washer Pumps Compatible Brands
  • Many pumps are. However, compatible replacement options do vary depending on your pressure washer’s engine shaft diameter & engine orientation, the original pump’s bolt pattern, and your engine's horsepower.

  • Your original pump was likely a strap-style (or bow tie) pump. That style isn’t made anymore. However, you can remove the spline and use your model number to find a replacement pump that you’ll install directly onto the shaft with a keyway.

  • Our pumps do require a keyway for installation onto the engine shaft. If a keyway is pictured in the listing, it will come with one. If you need to purchase one separately, you can do so from our catalog.

  • Many of our pumps don’t require oil maintenance, but some models do need oil changes. Generally, pumps with an oil vent port will need regular oil changes. Pumps without that port are sealed units and don’t need oil changes.

Fit perfectly on my Simpson Pressure Washer MSH3125-S. Pressure is a little lower than OEM but OK for normal use.

Good replacement; very easy to install. The pump seems better and stronger than the original and it costs much, much less than the OEM replacement

Just put this pump onto my two year old Simpson power washer that the stock pump crapped out on (basically one month after the warranty was done). The above mentioned Simpson model was four bolts, then line up the key on the motor shaft. I tested it briefly and it worked. Since it's September and a little cool, I won't be power washing to finish the house from when it crapped out.I'll repost this review next summer after using the washer to finish the house and deck which will give it a good workout.I'm going to store the washer in my basement instead of the shed instead of winterizing it. Not winterizing may have been the reason the original pump died.
